3-(4-Chloro-3-methyl-1h-pyrazol-1-yl)benzaldehyde CAS 1341649-60-2

Description

The occurrence of 3-(4-Chloro-3-methyl-1h-pyrazol-1-yl)benzaldehyde is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(4-Chloro-3-methyl-1h-pyrazol-1-yl)benzaldehyde (CAS 1341649-60-2), molecular formula C11H9ClN2O and molecular weight 220.65 g/mol, is a CATO reference standard with documented purity and traceability.

3-(4-Chloro-3-methyl-1h-pyrazol-1-yl)benzaldehyde (C11H9ClN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 3-(4-Chloro-3-methyl-1h-pyrazol-1-yl)benzaldehyde meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
